I am a ATH M50x fan. Sorry heefty. It is tough to try and sell someone on a pair of headphones when there is no baseline on what you like to hear. The HD598 are also a good buy. You may be abel to test them out locally as well. Some others my be the Fidelio X1 or DT 770 Pro (which are great value for $ right now.

One question none of us asked do you want IEMs, open, closed..

What are you looking for in a pair of headphones bass, good soundstage...

If you want to be patient and wait until you can get in on the Massdrop x Sennheiser HD6xx drop next round you won't find a better headphone for less than $200. The Massdrop x AKG K7xx is also very good at that price range. Both of these require you to deal with some Massdrop quirkiness and inconvenience. If you would rather have a stellar set of headphones for the price than have a set of headphones quickly that's the best route to take. It'll take more time but you'll get something much better for the money out of it.

For something you can pick up quickly I'd point you to the Sennheiser HD598 for open cans. For sealed, my personal favorite cans, the AKG K267 Tiesto can be found for that price range. You can get either of these from Amazon for less than $200

Those are my recommendations but you're undoubtedly going to get many suggestions to look at the ATH-M50X which I find horribly overrated and not worth the price. Many people also swear by Beyerdynamic and there are certainly a few sets of Beyers in that price range that are also decent. DT880 or DT770 to name a couple.
